OK since you're on the subject, along with Babies, small children, and people who won't close their blinds at night... what about people who have to grab your seat back and wrench it down in order to get into their own seat?! Or they even do it when they are walking down the aisle/waiting for the toilet queue!
There you are sound asleep (providing theres no screaming children nearby or flashing lights on the end of the wing coming in through the window) and all of a sudden.... BANG you're awake just cos the person behind is! Makes my blood boil!
